Delays due to diffusion of minorities are shown to constitute only a small part of the overall delay in vertically scaled devices. Instead, it is shown that charge- 20 storage in the emitter-base space-charge layer is the dominant E 10 delay. This sensitivity of the associated delay on the precise a band-gap structure near the EB junction is discussed.

This paper presents a SiGe differential low-noise amplifier (LNA) for the V-band. The measured gain at 60 GHz is 18 dB, and the input return loss is below -15 dB. The 3-dB bandwidth is from 49 GHz to 71 GHz. Measured and simulated S-parameters agree well over the whole range. The LNA draws 30 mA from a 2.2 V supply. It facilitates the design of a fully integrated WLAN receiver in the 57-64 GHz band.

bipolar SCR devices are studied as a potential ESD protection solution in case of a hi-voltage (25OV) process. The problem of the HBM-TLP (Human Body Model Pulse - Transmission Line Pulse) correlation is discussed based on pulsed measurements, ESD characterization and TCAD analysis, and is followed by a suggested new solution, based upon a multi-stage network and engineered to eliminate residual high turn-off voltage.

A 43-Gb/s full-rate clock transmitter chip for SONET OC-768 transmission systems is reported. The IC is implemented in a 0.18-mu m SiGe bicmostechnology featuring 120 GHz f(T) and 100 GHz f(max) HBTs. It consists of a 4:1 multiplexer, a clock multiplier unit, and a frequency lock detector. The IC features clock jitter generation of 260 fs rms and dissipates 2.3 W from a -3.6-V supply voltage. Measurement results are compared to a previously reported half-rate clock transmitter designed using the same technology.

In this paper we show that discrepancies that were occasionally observed in the base current mismatch area scaling of a 0.25 mu m bicmostechnology are due to a new mismatch phenomenon. We discuss how the cause of the effect was identified through electrical and TEM device analysis. These analyses helped to spot and solve a potential yield limiter in the technology.

In this paper, we present an integrated upconversion stage including an integer-N synthesizer in a 0.35 mu m bicmos process. This chip is, to our knowledge, the first integrated circuit for a DVB-RCT application ever published. This standard requires 125 KHz frequency steps in the UHF band and an architecture is proposed to upconvert the 44 MHz IF signal. The realization of a converter stage, composed of a mixer and a synthesizer, based on a multiband VCO (Voltage Controlled Oscillator), is also described. The mixer converts frequencies from 10801092 MHz to the UHF band (470-860 MHz). The synthesizer includes a programmable divider, with a dual modulus prescaler, and a multiband LC-VCO, which allows a frequency range of 1550-1952 MHz. A single side band phase noise of -84 dBc/Hz at 10 KHz offset and -122 dBc/Hz at I MHz offset have been measured at the synthesizer output. A power conversion gain of 7 dB and a noise figure of 14.9 dB characterize the mixer.
